PRINTING-TELEGRAPH.

SPECIFICATION forming part of Letters Patent No. 579,636, dated March 30, 1897. Application filed January 5, 1897. Serial No. 618,000. (No model.)

To all ZU7LO7IL it may concern:

Be it known that we, CHARLES L. BUCK- INGHAM, of the city and county of New York, and EMIL GERMANN, of Brooklyn, county of Kings, State of New York, citizens of the United States of America, have made a new and useful improvement in that class of printing-telegraphs in which messages are printed upon sheets of paper the edges of which are pasted or otherwise fastened together to form a tube, which is thereafter placed upon a stationary tube or support and given rotary and axial movement for feeding the same from one letter or space position to the next and from line to line throughout a message, of which the following is a specification.

In our application for patent, Serial No. 604,208, filed August 28, 1896, we have shown and described a machine the purpose of which is to positively effect a rotary and axial feed of the paper tube in which we employ an escapement-wheel, subject to the continuous propulsive action of a motor, having a number of teeth equal to the numberof characters in each line upon the page. Such escapement-wheel is directly connected through a train of spur-wheels with the paper tube in such manner that from the beginning to the end of the message the sheet is positively and mechanically geared with the escapement-wheel; that is to say, the paper tube is fed circumferentially step by step for each letter and axially from line toline under the direct action of the escapement-wheel and a train of gearing which directly connects the paper tube with said escapement-wheel; and as a special means for effectingsuch gear connection there is provided in the lap or double thickness of paper, where the edges are pasted together, a line of perforations into which the teeth of a small spur-wheel, positively joined with the escapement-wheel, are in mesh throughout the printing of the message. The small spur-wheel is preferably carried within a large annular gearwvheel in train with the escapement mechanism, while the teeth of such small spur-wheel project not only through the perforations of the paper tube, but into grooves surrounding the stationary support around and along which the paper tube is'moved, such grooves being for the most part in planes at right angles to the axis of the stationary support and at one point in diagonal planes.

While the teeth of the small spur-wheel are within the circumferential grooves, the paper tube has only rotary movement, but when passing through the diagonal slots the teeth of the wheel are given a rotary movement, thereby moving the paper tube axially for a new line, as well as causing rotation. A slot across the ridges between these grooves is cut at an initial point, so that during the removal of a blank upon which a message has been printed and the insertion of a new blank the spur-wheel is left free to rotate. In order, however, that the teeth of the spurwheel may find their way into the grooves upon the commencement of a new line, it is found necessary to employ some means by which said teeth shall be set in a definite angular position, and to this end in said application, Serial No. 604,208, a check-wheel and spring were employed to hold said spur-wheel in any one of several positions, particularly as shown in Fig. 6 of the drawings of said application. The employment, however, of such a device rendered the insertion of a tube at the beginning of a message difficult. Moreover, in passing from the termination of one line to the beginning of the next throughout the printing of a message such checkwheel afforded considerable resistance, thereby materially impeding the longstep movement.

Our present invention has for its object to dispense with such check-wheel and spring, thus leaving the small feed-wheel in its initial position free to rotate and mesh with the holes of the paper tube, while at the same time the teeth of the wheel, upon the first step of its feed, are accurately directed within the grooves surrounding the stationary support.

Figure 1 represents a general view of our machine. Fig. 2 is a plan view showing the type-wheel, the stationary support, paper tube, and apparatus for giving the messageblank rotation. Fig. 3 represents a section of the stationary support, showing the circumferential and diagonal grooves surrounding the same and the slot parallel with the axis within which the feed-wheel may rotate 2 erases at its initial position or that position at which a new message-blank is inserted. Fig. 4 represents a small block within which the diagonal grooves are formed, and which is thereafter inserted within the stationary support with the diagonal grooves matching with those surrounding the tube. Fig. 5 shows a small feed-wheel the teeth of which mesh within the grooves surroundin the stationary support and the holes of the paper tube, together with a directing-guide for circumfercntially adjusting the small feed-wheel so that its teeth shall pass within the circumferential grooves of the tubular support at the first feed of the message-blank. Fig. (3 is a sectional view showing the stationary support, the train of gear for rotating the paper tube, and mech anism for eircumferentially adjusting the small wheel by which the paper tube is carried.

Referring to Fig. 1, n represents a smooth metallic tube rigidly supported at its right end upon a bracket 1), affixed to a base-plate Upon the tube a is placed a sheet of paper formed into a tube by pasting or otherwise fastening its edges together, and upon this tube messages are printed line by line in page form. i

As shown in Fig. 2, the sheet of paper is formed into a tube T, whose overlapping edges when pasted together are perforated with a line of holes 7L 7!, into which the teeth of a small spur-wheel f", Figs. 5 and G, are in mesh, whereby the tube may be given a circmnferential feed a step at a time for each succeeding letter and axially from line to line in forming the page. The train of gearing for conn ect-ing the escapement-wheel with the paper tube is represented in Figs. 1, 2, and 6. In this connection j is a ratchet-wheel upon whose shaft is rigidly fixed a wheel 1', which meshes with a wheel 7;, upon the shaft of which is placed a larger wheel 7. in turn gearing with a large ring-wheel I, which surrounds the tubular support a, and which is supported upon friction-rollers on m a n. The ringwheel Z is of a diameter considerably in excess of that of the supporting-tube a and sufficiently greater to enable the mountin of a small spur-wheel f within the annulus in such relation that the teeth of f shall project through the holes in the paper tube into circumferential ordiagonal grooves formed in the periphery of the tubular support. Thus as the escapement or step-by-step wheel j is permitted to rotate its movements are imparted by way of spur-wheels 1' 7t 7t" Z to the spur-wheel f, the teeth of which, projecting through the holes of the paper tube, carry the latter circumferentially from one letter position to the next around the stationary tubular support. This train of gear is subject to a continuous propulsive action from a motor 6, Fig. 1, gearing with a shaft (1, which in turn, by a beveled gear f g, imparts a winding tendency to one end of a coiled spring, the other end of which is connected with the shaft upon which the spur-wheel t' is mounted, and by this means with each movement of the escapement-pallets which control wheel j the train of wheels connectingj with the wheel f, meshing with the paper tube, are given a step of rotation. The teeth upon wheel j, with the exception of a blank portion, are equally spaced over its periphery and are of a number equal to the characters in each line of the printed message, while that portion of the periphery upon which no teeth appear is of sufiicient length to permit an abnormal step-a step usually made equal to six or seven of the shorter steps and it is by this means that the paper tube is at a single step of the escapemcnt permitted to rotate a distance representing the two margins of the printed page. The escapement referred to is operated by magnet M and an armature It, which is pivoted upon a shaft Pt, upon which is carried a suitable bracket and pawls 4- and 5, the pawl 5 being fixed with reference to its supporting-bracket,wl'1ile i is movable around an axis 6. By this means as armature R is attracted pawl 5 is drawn into a space between the teeth of the ratchet-wheel, while pawl 4c is disengaged. This action, however, permits the escapement vheel to move only a very short distance, while at the same time pawl at is disconnected from the wheel and, by means of a spring 21., is caused to move backward in a direction opposite to the rotation of the escapemcnt-wheel and into such a position that upon the retraction of armature it said pawl will drop into the next notch just before pawl 5 is disconnected. In other words, just before disengagement of pawl 5 pawl 4 is thrown into that cavity of the wheel next back of the one which pawl 5 had left, thus leaving the wheel, under the action of the propelling-niotor, free to rotate an additional step.

In the specific form of apparatus here shown is represented a ring-wheel Z, having horizontal projecting edges or flanges s and a surrounding series of spur-teeth. By this means wheel Z- is easily mounted and retained in position, meshing with spin wheel 7;, since by this construction the friction rollers or guides on m n it, having central grooves, support the wheel both circum ferentially and axially; that is to say, the peripheries of these rollers serve as guides and supports for the flanges s 3, while their central groove affords a passage-way for the spur-teeth of the wheel, the sides of said grooves at the same time serving to hold said wheel in a definite axial position. Upon the inner periphery of wheel Zis affixed a bracket or shoe (particularly shown in Fl 5 and (5) within which is pivoted the small spurwheel f, which meshes with the holes in the paper tube. As here shown, a I) serve as journal-supports for the shaft 9 of wheel f and are connected together by a yoke c in such manner as to form a convex surface littin g the inner periphery of wheel Z.

Preparatory to the printing of a message spur-wh eel f is brought into a predetermined position with reference to the tubular support, and while f is in this position the tubular blank is pushed along the support until the first holes in the lap of the tube are brought into mesh with its teeth. The particular means by which this is accomplished are shown in Fig. 3, in which is represented a small slot u, out into the tube lengthwise slightly at one side of the diagonal grooves '12 w 00. If wheel f is brought into the plane of the slot u, obviously it may be rotated and the paper tube may be thrust forward, since the teeth of f will finda clearance in the slot and will at the same time mesh with the holes h of the tube T. To accomplish the circumferential feed of the, papertube, wheel f is circumferentially swept around the tubular support (1, its teeth at the time being stationary with reference to its own axis, they being held within the circumferential grooves r s t of the tubular support, as shown in Figs. 3 and 5. At the end of each line of the message, however, the teeth of the wheel are brought to the inclined grooves 12 w 00, and by this means wheel f is given rotation equal to the angular space covered by two of its teeth and a distance sufficient to move the paper from one line position to the next, and it is by this means that the paper, while given a circumferential rotation over its long step representing the two margins of the page, is also moved axially a sufficient distance for a new line. To the end, however, that the teeth of wheel f may move freely past the slot to, the inclined grooves o w x are terminated a short distance to the right of the slot, whereby the teeth of the wheel in normal operation after passing the inclined grooves may find their normal position within the planes of the circumferential grooves before reaching the position of the slot. To further insure against the catching of the teeth of f in passing slot a, a setting device is employed, which constitutes the novel feature of this invention.

In carrying out our invention we employ manual means for connecting and disconnecting the escapement-wheel from its pallets, whereby at the end of a message, if only part of a line has been printed, the escapementwheel and its accompanying gear may immediately return to a zero position, and We further employ such manual apparatus for also connecting the motor-train for driving the sheet of paper with a fiy-train or retarding apparatus, whereby upon releasing the escapement-train from its pallets it may be moved to a unison position without undue shock. Such manual apparatus is also employed for setting wheel f into such position that its teeth shall find the grooves r s t at the first step upon the commencement of a message.

As shown in Figs. 1, 2, and 6, m is a rod which when pulled to the left disconnects the escapement-wheel from its pallets and joins with the driving-train a fly 13. Connecting with this rod is an upright stud 27, to which is attached a cord 28, passing under a grooved wheel 29, upward over wheel 30, and thence to a stud 43, which is attached to a sliding bar 35, the latter being supported in its various positions upon an arched bracket 31. The arched support 31 is provided with oblong holes 32, 33, and 34, and within these openings pass bolts 36, 37, and 38, which are attached to bar 35. Also rigidly fixed upon bar 35, as shown in Figs. 2, 5, and 6, is a downwardly-projecting-arm 39, to one end of which is a wedge-formed guide, the point of which may, when wheel f is in its normal position, be thrust between any pair of teeth in such relation as to move wheel f,whereby its teeth must find the grooves r s t after leaving slot u at the commencement of a message. To the right end of bar 35, Fig. 6, is connected one end of a U-spring 41, the other end of which is fixed upon the arch support 31. From this arrangement it will be seen that when rod on is pushed in cord, 28 will be pulled downward, thereby drawing the carrier 35 to the right, as shown in Fig. 6, and with it the setting-point 40, or into a position to set the teeth of wheel f into their proper position, both at the commencement of a message and at all times in the printing of a message as the blank is being rotated over its long step and while wheel f is passing the slot to. It will also be seen that at the same'time the escapement-wheel is thrown in gear with its pallets, while the fly is disconnected from the driving-train. Upon pulling rod m to the left, however, the carrier 35 is thrown to the left by spring 41, and with it the point 40, thus carrying said point backward out of the path of the teeth of wheel f, leaving the latter free to rotate within the slot to at the insertion of a paper tube for a new message. In other words, our invention consists in employing with the pull-rod which connects and disconnects the escapement-wheel from its pallets a movable cam or guide for setting the teeth of wheel f into proper position after said wheel has been left free to rotate within slot u for the insertion of a 1nessage-blank.

What we claim, and desire to secure by Letters Patent, is-
